# How to Apply the det & determinant Functions in R (2 Examples)

This article illustrates how to compute the determinant of a matrix object using the det and determinant functions in the R programming language.

## Example Data

x <- matrix(4:1, nrow = 2) # Construct matrix in R x # [,1] [,2] # [1,] 4 2 # [2,] 3 1 |

x <- matrix(4:1, nrow = 2) # Construct matrix in R x # [,1] [,2] # [1,] 4 2 # [2,] 3 1

## Example 1: Get Determinant of Matrix

det(x) # Using det() function # [1] -2 |

det(x) # Using det() function # [1] -2

## Example 2: Get Modulus of Determinant on Logarithm Scale

determinant(x) # Using determinant() function # $modulus # [1] 0.6931472 # attr(,"logarithm") # [1] TRUE # # $sign # [1] -1 # # attr(,"class") # [1] "det" |

determinant(x) # Using determinant() function # $modulus # [1] 0.6931472 # attr(,"logarithm") # [1] TRUE # # $sign # [1] -1 # # attr(,"class") # [1] "det"
